My old new Linux machine

So, I realised that while my Pi 400 will run LMMS, it only runs older versions (due to its ARM chip?), and not the VSTs (soft synths) that I want to play with. So I took my old Lenovo ThinkPad, and reflashed it with Linux (Ubuntu Studio). It now whizzes along with LMMS, Audacity and Kdenlive. I have had some problems getting individual VSTs installed (I still don't get what WINE really does if it's not an emulator), but I am in the VST business. Which begs the question - what shall I do next with my Pi 400? How about going right back where I started, with Sonic Pi?
